beacon.validator.exit_queue_latest model provides the estimated epoch and timestamp where a validator is expected to exit.
The estimated exit and withdrawable epochs are based on the current churn rate and the validator’s position in the exit queue at the time of the snapshot. As with beacon.validator.entry_queue_latest, these are approximations: the outputs are expected to vary around +/- 1-2 epochs as churn rate and queue depth change.
This model is derived from beacon.validator.balances_latest and is updated approximately every 30 minutes. The state of the validator will indicate which epoch it is expected to exit and available for withdrawal.
